For his successes he was named the GREAT.
CONSTANTINE THE GREAT (306-337).
Constantine determined to build for his Empire a new capital, which should be worthy of him.

He selected the site of BYZANTIUM as offering the greatest advantages; for, being defended on three sides by the sea and the Golden Horn, it could easily be made almost impregnable, while as a seaport its advantages were unrivalled,--a feature not in the least shared by Rome.

The project was entered upon with energy; the city was built, and named CONSTANTINOPLE.

To people it, the seat of government was permanently removed thither, and every inducement was offered to immigration.

Thus was born the GREEK EMPIRE, destined to drag out a miserable existence for nearly a thousand years after Rome had fallen a prey to the barbarians.
